8.1.4 TRACKING MODE
The Scorpio systems have fully encoded information regarding the position of the crane and the head
in space. From a reference point called Zero Position, the system knows how many degrees the crane
or the remote head has changed in every axis. This is why it is important to set the Zero position of
the remote head and the crane always the same: with the camera facing the column of the crane in
the horizonal position (see chapter 8.1.2 Set up).
With that information, the Motion Generator allows the system to
generate one tracking point in the space and to keep the camera
looking to that point even if the crane change the position of the
camera in the space (fig. 08.12).
The only thing that the system needs to know is where to generate
the tracking point. The way to do this is by giving to the system the
distance from the center of the remote head to the point to be tracked.
It is important to notice that it will always be possible to move the
remote head from the control desk. The only difference is that instead
of moving the axes of the head, the user will be moving the tracking
point in the space depending on the distance to the tracking point. This
can be used to readjust the point where the shot requires.
Depending on how the distance to the tracking point is introduced to the system, there are three
different modes: Manual, Focus M., and Focus. To use the Focus M. and the Focus modes a Scorpio
Focus or a Servo Lens Control needs to be connected to the system, otherwise they will not be
displayed.
MANUAL DISTANCE
When the distance manual mode is
selected, we can introduce a distance
to set the tracking point. If the number
between the brackets in the
DISTANCE MODE tab is pressed, a
keypad will be opened to introduce the
distance between the camera and the
target. Measure this distance from the
center of the head. The minimum
distance is always 0.20cm (7.8 inches).
There is also the possibility to reverse the pan and the tilt corrections depending on the model of the
head or in case the head is mounted over slung and the corrections in those axes are in the wrong

same point.
Note: This function is not a Motion Control, there are some
tolerances to consider when using this function. In order to
minimize these deviations, introduce the minimum distance
as possible to the point to be tracked (approach the camera
to the target). The minimum distance is 0.20m (7.8 inches)
